DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 642,635, dated February 6, 1900. Application filed J une 10,1899. Serial No. 720,059. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN S. SHRAWDEE, a citizen of the United States, residing at Collegeville, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Dumping' Vagons, of which the following is a specification. 1

My invention has relation to a dumpingwagon of that type in which the frame and body of the vehicle are supported upon vfour wheels, and in such connection it relates more particularly to the construction and arrangement of such a vehicle. l

The principal object of my invention is to provide a four-wheeled dumping-wagon of comparatively simple and inexpensive construction and which shall be strong, durable, and easy of manipulation. l y

To this end my invention consists, first, in providing ina four-wheeled dumping-Wagon a front truck comprising a substantially rectangular frame having double sides which form the bearings for the axle of each front wheel; second, to provide,`in connection with the front truck, a main trucksupported above the front truck to constitutea support for the wagon-body, Vsaidvmain truck extending rearwardly on each side of the wagon-body and projecting downwardly at its rear end to constitute the bearings for the axles of the rear wheels; third, to lprovide in such a vehicle, in conjunction with the front and main trucks, a king-bolt of substantially inverted- T shape, the two members of which king-bolt being respectively swiveled to themain and to the front truck; fourth, to provide in such a vehicle, in conjunction with the main truck, a brake mechanism for the rear wheels of peculiar construction and arrangement, and, fifth, to provide in such a vehicle, in conjunction with the main truck and the body of the vehicle swiveled thereto, a .locking and re- -leasing mechanism of peculiar construction ed and arranged in substantially the manner hereinafter described and claimed.

The nature and scope of my invention will be more fully understood from the following Fig. l, partly sectioned and broken away.

Fig. 3 is an underneath plan view of the .vehicle. Fig. at is a front elevational view of the vehicle, partly sectioned; and Fig. 5 is an enlarged perspective view villustrating the locking and releasing mechanism.

Referring to the drawings, d represents the body of the vehicle, swiveled upon a shaft a', which is supported in the double side frames b b of themain'truck. The frames b b are connected together by means of the shaft a', the diagonal braces b', and the two cross-bars b2 and h3, located below the front end of the vehicle. Depending from the front end of the main truck are two substantially U- shaped brackets forming the bearingk for the vertically-disposed member d of a substantially inverted-T-shaped king-bolt. To the horizontal member d of this king-bolta rectangular shaped front truck is swiveled. This truck is formed of the side bars e e, connected-at either end by double end bars e' e', which bars form, respectively,`the vbearings or supports for eachv axle f f of the front wheels f' f. s

From the above description it will lbe understood that the front truclg'together with the wheels j" f', can be turned beneath the body either with the vertical member d or the horizontal member d' of the king-bolt as a fulcrum. The truck and wheels can therefore gow either swing in a horizontal plane beneath f `the handle in required position.

Lthe `body down upon the main truck.

either end a *brake-shoe la', adapted to be pressed against the tires of .the wheels g g. Intermediate of the ends of the beam k eX- tends an arm k2, slottedly connected, as at` 7c3, with a crank 7s, depending from the transverse brake-shaft 755.

spring-controlled catch k7, adapted to engage in `the notches of a quadrant-plate ks to lock The brakebeam c is swn ng at either end upon thehooks ko, swinging loosely in bearings k1", depending from the spanners or braces h6.

The locking and releasing mechanism by means of which the body a of the wagon is secured to or released from the main truck ofthe vehicle consists of a transverse shaft m, adapted to oscillate or rock in bearings m', depending from the front end of the main truck between the two cross-bars b2 and b3. On the shaft m is secured a catch or latch m2, having its hook end m3 normally elevated under the `tension of a spring` m4, which tends normally through a pin 'm5 to depress the other end of the catch m2. The shaft m is provided with a handle m, by means of which it may be turned to throw the hook end m3 of the catch m2 either up or down. The front end of the wagon --body is provided with a notchor recess m7, into which the hook end m3 of the catch m2 is adapted toenter to lock When the `catch is released from the recess or notch m7, the body d is readily swung upon the shaft a until its contents are `discharged `from the depressed rear end of the body. The rear portion of the body is permitted to swing down between the side frames of the main truck and the two rear wheels.

Having thus described the nature and `objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a four-wheel du mping-wagon, a front truck, comprising a substantially rectangular frame having double sides to .form the bearings for the axles of the front Wheels, substantially as and for the purposes described.

2. In a four-wheel dumping-wagon, a main truck upon which the body of the vehicle is swiveled and supported and comprising two double side frames arranged outside the The shaft h5 is preferi ably su pported below the spanners or bracers h6 b and is operated by a 'handle 766, having a` `wagon-body `and extending downwardly and horizontally at the rear ends to constitute body and projecting downwardly to form bearings for vthe rear wheels, a front truck located below the front end of the main truck and forming bearings for the front wheels,

and a substantially inverted-T-shap'ed king- `bolt connecting the main truck and front trucks together, the front truck and wheels being swiveled to the `main .truck with .the king-bolt as a fulcrum so that said front truck may turn in a horizontal plane below the main truck and ina vertical plane towardior away fromthe main truckpsubstantially Las and for the purposes described.

4. `In a four-wheel dumping-wagon, a body, a main truck to which said body is swiveled, a transverse shaft adapted to bcoscillated or rocked in bearings.dependingfrom the front end of said main truck, a catch secured on said shaft and having its `hooked end `normally elevated under the tension of a spring tending through a pin to depress the other end of said catch, a handle connected with saidshaft and adapted to turn the same to `throw the hooked end of said catch either up or down and the front end of said body being provided with a notch `or recess into which the hooked end of said catch is adapted to enter to lock said body down upon said main truck, substantially as and for `the purposes described. i

5. In a four wheel dumping wagon, a wagon-body, a main truck upon which said bodyis supported and comprising twodouble side frames arranged outside of said wagonbody and forming the bearings for `the axles of the rear wheels thereof, said frames connected together by' `means of a shaft, two diagonal braces and crossbars and located below the front portion of said body, whereby is prevented torsional strain uponsaid truck in the action of the wagon, substantially as and for the purposes described.

In testimony whereof. I have hereunto set my signature in the presence of two subscribing witnesses.

JOHN S. SHRAVDER.
